I would count this as 2/3 of 100.
This is a lot of entrees for 65 people, which makes it harder to estimate.
A full 6 foot sub is 25 servings.
meatballs- 8-10 pounds- mostly eaten as appetizers
arroz con pollo- about 25 servings (40-50 pieces of chicken)
sausage and peppers- You could skip this or the meatballs- 8 pounds sausage, equal weight veggies
chicken nugget & fries (for the kids)- About 100 nuggets- the grown ups will eat them too, as appetizers
penne with vodka sauce- unless this is a family favorite or specialty, I suggest you go with a more kid-friendly sauce; about 8 pounds of pasta. You will have some left, because of the rice, but with this menu, it is very difficult to guesstimate who will choose what.
I would definitely add a green salad or relish tray, or an antipasto tray would take care of the appetizer issue.
